First AMD Ryzen 5 2500U benchmarks shared

[HEXUS]

Matches the Intel Core i5-8250U for CPU grunt, but doubles up on GPU performance.

Same CPU performance, far better graphics performance, and over $200 less? AMD really did pull out the stops with Ryzen.

Lets hope that fanboys are courageous and choose what is best, not the badge.

Power consumption under witcher 3 load was impressive.

Also worth remembering that this is the second rung chip with less GPU shaders. CPU performance of the Ryzen 7 2700U won't be much different, but 25% more shaders should push it up to around GTX 1030 (MX150) levels as long as the memory bandwidth doesn't restrict it too much....

I'd love to know what the GPU performance would lose in a single channel configuration. The upcoming 13" Lenovo might just be my perfect next laptop, but if the single channel memory cripples the GPU....

If only it were just down to performance of integrated graphics...

Although the integrated graphics are faster than i5-8250U it's slower than an MX150 so any reasonably good discrete graphics make faster integrated graphics a redundant statistic, a lot of larger laptops do come with discrete graphics. Also, graphics performance to a lot of buyers is not a primary concern, Intel graphics are fine for a business user who will care a lot more about the rest of the machine, if AMD mainly get design wins for 15" consumer grade machines with the aesthetics of an old brick then it won't matter how good the CPU is, nobody will want them in large quantities.

The HP machine looks OK but it's still a 15" machine that weighs over 2Kg, I wouldn't buy it to lug around if it had desktop 1080Ti graphics performance. Lets hope there are also some 12-14" designs that can compete on weight with the better business class laptops, around 1.2-1.6Kg depending on size.

Per the launch announcements (http://hexus.net/tech/news/cpu/11147...vega-graphics/) there's going to be at least one 13.3" laptop in the pre-Christmas releases with a peak weight of 1.14kg. Only downside to that one is the single channel memory, but I strongly suspect other companies will create similar machines with dual channel memory. A lot depends on how well AMD have managed their OEM relations this time around - but since they're performance-equivalent to Intel's direct competition parts (4C/8T/15W) it should encourage more OEMs to put them in premium laptops.

Also, there'll be a cheaper APU on smaller silicon (2 core + 3 CUs) for the bulk market, which should compete nicely with Intel's mainstream 2C/4T offerings ...

Fit another memory stick once you've bought it? I was able to order a "custom" laptop straight from lenovo with extra memory (it was a thinkpad, hopefully the consumer-er ones aren't too different?), and it cost less at the time than it would have to buy the memory separately online

Given the slides AMD put out specifically state that it's a single channel device, I don't think that'll be possible sadly. If they hit the market and it turns out it can use dual channel memory then it'll be a no brainer But I honestly can't see why they'd release a dual channel device but say it's only single channel...

For me, these are at least as important as the desktop CPUs.
Intel have had the laptop market to themselves for too long, more even than desktops.
These are brilliant, if the charts to date are proportionate and representative.

A lot of the smaller laptops coming into the office at the moment (Lenovo X270 for example) only 1 RAM slot, sometimes RAM is partially soldered to the motherboard but that's usually 4-8GB (i.e. the base amount) so you wouldn't be properly dual channel if a 16GB stick was in the only slot.

I've had a look at the reviews for the Intel-equipped 720s and the only that mentions it reckons that all of the memory is soldered with no SODIMM slot available.

That said, the Intel version houses an i5 7200U and a GeForce 940MX, so has to cram a lot more hardware in and dissipate a lot more heat. No wonder they've jumped on the Ryzen 5 - should provide better performance in a smaller package generating less heat...!
